ROBERT KLECKNER, OF HIGHBRIDGE, NEW JERSEY.

NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 735,116, dated August4, 1903.

Application filed October 11,1902. Serial No. 126.912. (No model.)

To aZZ whom it may concern:

Be it known that 1, ROBERT KLECKN-ER, a citizen of the United States,residing at Highbridge, in the county of Hunterdon and State of NewJersey, have invented a new and useful Improvement in Nut-Locks, ofwhich the following is a specification.

This invention relates generally to nutlocks, the object being toprovide an exceedingly cheap and simple device by means of which a nutcan be securely fastened upon a bolt.

My invention is particularly adapted for the use of a railroad-rail butit will of course be understood that it can be used any place whereverit is desired to securely fasten a nut upon a bolt; and, broadlyspeaking, the invention consists of a threaded washer split radially,one end being forced slightly below the opposite end and adapted to bindagainst the fish-plate or other solid object, said washer having anotched or recessed boss adapted to engage one edge of the nut.

The invention consists also in certain details of construction andcombination, all of which will be fully described hereinafter andpointed out in the claim.

In the drawings forming a part of this specificatio'n, Figure 1 is aperspective view showing the practical application of my invention asapplied to a rail. Fig. 2 is a side elevation of the threaded end of thebolt and looking device engaging therewith. Fig. 3 is a face view. Fig.4c is a detail perspective view of the locking-washer.

Referring to the drawings, A indicates an ordinary railroad-rail, B thefish-plate, O the bolt, and D the'nut, all of said parts being-of theusual or any approved construction. The

locking-washer E has a threaded bore E and is split transversely fromthe bore to the outer margin, forming two adjacent ends E E and thewasher being of flexible material the ends are adapted to be forcedapart, one end being forced below the plane of the other. On theopposite side of the Washer is formed a boss E, which is notched on itsinner side at E and is adapted to engage one edge of the nut. In use thewasher and nut are placed on the bolt and the nut turned, so that oneedge will fit into the notch E When the nut has been turned intoposition, the ends of the washer will be forced apart and out ofalinement with each other. The washer being securely held by this edgeit will be impossible for the washer to turn, and so long as said washerremains stationary the nut will be held firmly in place.

While I have described the washer as having a threaded aperture, it isobvious that the said aperture may be made smooth, inasmuch as the nutand washer are always placed upon the bolt together.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is

A nut-lock comprising a washer having a threaded bore and splittransversely, one end of said washer being adapted to be forced out ofalinement with the other end, and a notched boss on the side of thewasher opposite the split portion, said boss being adapted to engage oneedge of the nut.
